1.
The simulation results show,that when the nonlinearity is weak,the NSW power distribution maintains its cosine type,but there is a pitch modulation effect,which will be shorten when the power increases,and it is proportional to the geometric mean of maximum and minimum indices.
结果表明,当非线性较弱时,驻波的功率分布仍然呈余弦形式,但将出现节距随功率增大而变小的节距调制效应,并正比于最大和最小折射率的几何平均值。
